What Our Members Are Saying about the Real Gas Mileage of the Chevrolet Cobalt

Chevrolet Cobalt Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2010	2dr Coupe 155-horsepower 2.2L I4 4-speed automatic FWD	Around town it's not great, but out on the open road mileage almost doubles. see full Chevrolet Cobalt review
2009	2dr Coupe turbocharged 260hp 2.0L I4 5-speed manual FWD	The fuel economy is very good considering the performance available. I typically get better than 25MPG with a fair bit of city driving and fairly heavy throttle. see full Chevrolet Cobalt review
2009	4dr Sedan turbocharged 260hp 2.0L I4 5-speed manual FWD	In mixed driving I get 25 - 26 MPG, even with 75 mph stints and popping in and out of traffic. In pure highway, gets 28+ at 70+ see full Chevrolet Cobalt review
2008	4dr Sedan 148-horsepower 2.2L I4 4-speed automatic FWD	Better than most North American cars. Lower carbon footprint. Cheaper to run. see full Chevrolet Cobalt review
2007	2dr Coupe 173-horsepower 2.4L I4 5-speed manual FWD	Under good highway driving conditions the Cobalt can go 700km on a single tank, but even in harsh conditions fuel economy is reasonable. see full Chevrolet Cobalt review
2007	2dr Coupe 148-horsepower 2.2L I4 4-speed automatic FWD	Most neighbors report 35 mpg on hyway. here we do mostly high spped highway. see full Chevrolet Cobalt review
2007	2dr Coupe 173-horsepower 2.4L I4 4-speed automatic FWD	I like that the 2.4L engine is able to put out significantly more power than the 2.2L and keep the same economy. The SS 2.4L is pretty quick and fun to drive and I still get 28 mpg on average just gunning around town with a lead foot and about 20% high see full Chevrolet Cobalt review
2007	2dr Coupe 148-horsepower 2.2L I4 5-speed manual FWD	While not as impressive as some of its competitors, the Cobalt is still good for low to mid 30s if driven properly. see full Chevrolet Cobalt review
2007	2dr Coupe 148-horsepower 2.2L I4 4-speed automatic FWD	34 MPG observed - and this from a roomy stylish car that cost me less that 15,000 see full Chevrolet Cobalt review
2007	2dr Coupe 148-horsepower 2.2L I4 4-speed automatic FWD	While the Cobalt may only get 23mpg in real city driving with a heavy foot, it is still relatively easy to achieve 28mpg in the city and 35+mpg on freeway. see full Chevrolet Cobalt review

2009	4dr SUV 240-horsepower 3.0L V6 6-speed automatic FWD	Coming from a Trailblazer, we like the average of 21-22 MPG in mixed driving, as were used to about 17 MPG. Fuel economy climbs toward the rated 26 MPG the more highway driving we do. see full Mercury Mariner review
2007	4dr SUV 200-horsepower 3.0L V6 4-speed automatic AWD	For the first almost three years after we got the car, it gave 21+ mpg in town & 24+ mpg on the road. see full Mercury Mariner review
2005	4dr SUV 153-horsepower 2.3L I4 4-speed automatic AWD	For an SUV with a 4cyl and 4wd I get avg of 22 MPG mixed city and highway. I usually get 23-26 on freeway only. This is good. see full Mercury Mariner review

Mercury Mariner Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2007	4dr SUV 200-horsepower 3.0L V6 4-speed automatic AWD	For some reason when new Michelin All Terrain tires with Nitrogen air replaced the Champions from the factory, it plummeted to 17 & 20 mpg. No explanation from Michelin, Costco or Ford/Mercury - they have no idea why. see full Mercury Mariner review
